  • Patent number: 5917056
    Abstract: The present invention relates to novel 10-deacetyl-14.beta.-hydroxybaccatine III derivatives. The novel derivatives, having cytotoxic and antitumour activity, are prepared from this synton after functionalization of the hydroxyls at 1-, 14- as thiocarbonate, iminocarbonate and sulfite and possible oxidation of the hydroxyl at C.sub.10. These derivatives are subjected to a subsequent esterification at position 13- with a variously substituted isoserine chain. The products of the invention can be administered by the injective or oral route, when suitably formulated.
